slic

i have tried to find out what slic version im running for using windows 7 as genuine but failed

i ran rw opened acpi table but couldn't find the slic tab
im running the program under windows xp sp3 does this matter?
i just want to know my slic version to know if im able to use this method
i have also tried SLIC_Dump_ToolKit but "Dump Error ! (SLIC Table Not Find ! )"
any help? thanks
